Abstract
Higher brain functions require the precise spatiotemporal coordination of neuronal activity across multiple brain structures. Neuronal oscillations have been strongly implicated in this coordination via a mechanism termed “communication through coherence”, i.e. by modulating the functional connectivity between structures via a modulation of phase coherence. Multiple studies have provided experimental evidence for task-dependent “modulation through coherence” linked to motor and cognitive functions. However, the mechanisms controlling the modulation of coherence remain unknown. I will present results from our research supporting a proposed role of respiration as a fundamental rhythm for brain-wide temporal coordination of slow neuronal activity and of a crucial role of the cerebellum in the task-dependent modulation of coherence at a millisecond time scale.
